R22 Vs R290
R22 is a hydrochlorofluorocarbon (HCFC) that is used in most air conditioners. These refrigerants are better than CFC, but still, they can damage the ozone layer. That is why the Indian government has decided to phase out R22 by 2030.
R22 is widely utilized in air conditioners, heat pumps, dehumidifiers, refrigerating dryers, cold storage, food refrigeration equipment, marine refrigeration equipment, industrial refrigeration, commercial refrigeration, refrigeration units, supermarkets display, and display cabinets, etc.
R290 is a new environment-friendly refrigerant. Mainly used for central air conditioning, heat pump air conditioning, household air conditioning, and other small refrigeration equipment.
R290 has zero effect on the ozone layer. Most of the premium air conditioners are coming with R290 nowadays.
R32 Vs R410
R32 primarily replaces R22, which is a gas at room temperature and a colorless transparent liquid at its pressure. It is easy to dissolve in oil and water. Although it has zero ozone depletion capacity, it has high global warming potential, which is 550 times higher than carbon dioxide every 100 years.
The global warming coefficient of R32 Soft is 1/3 of that of R410A, which is more environmentally friendly than R410A and R22 Soft, but about 3% of R32 to R410A refrigerant
The working pressure of R410A is about 1.6 times that of normal R22 air conditioners, and therefore the refrigeration (heating) efficiency is high.
R410A Soft contains two quasi azeotropic mixtures, R32 and R125, each containing mainly hydrogen, and fluorine.
R410A is recognized internationally as the most suitable refrigerant for replacing the current R22 and has been popularized in Europe, America, Japan, and other countries.
The R410A is primarily used to replace the R22 and R502. It is clean, has low toxicity, non-water, and good refrigeration effect characteristics, and is widely used in household air conditioners, small commercial air conditioners, and domestic central air conditioners.
